It's literally impossible for a consumer to evaluate all the materials, labor, and external effects involved in all the products they encounter or are effected by. Even then, if they identify something they find unacceptable, how do they avoid it if it's related to a necessity and it's an industry standard?

How do you propose the consumer has any realistic chance of having a say in these matters other than collectively empowering a group of people to look into it and enact recommendations and rules?
